Summary: The study investigates the absorption enhancement of atmospheric black carbon (BC) through the lensing effect when mixed with non-BC/coating material. The results from field observations show both large and minor absorption enhancement factors for different BC-containing particle populations with large bulk non-BC-to-BC mass ratios. The study highlights the importance of considering mixing-state heterogeneity in optical models to accurately estimate the aerosol radiation effect of BC.

Summary: This study investigates the size distributions of black carbon (BC) particles in urban, suburban, and background sites in China. The results show that the BC particles were composed of thinly or thickly coated aerosols. The mean number fractions of thinly coated BC aerosols were highest in the suburban site and lowest in the background site. The study also found that about 10% of the BC-containing aerosols were attached to non-BC components. These findings can be used in modeling studies to better understand the uncertainties of the BC radiative effects.

Summary: The study in Wuhan shows that black carbon concentration in the atmosphere varies seasonally, with the highest aerosol optical depth in winter and the highest total aerosol concentration in summer. Under polluted conditions, aerosol and black carbon radiative forcing is strongest in summer, while black carbon radiative forcing is increased in both summer and winter compared to clean-air days. The results highlight the significant impact of particulate air pollution on radiative forcing.

Summary: Research on the polarized radiative transfer of black carbon (BC) aerosol particles is important for climate change monitoring. However, existing studies have not considered the effects of complex morphology and heterogeneity of BC aerosol particles. This study proposes a general method for calculating the polarized radiative transfer of heterogeneous BC aerosol particles with arbitrary coating shapes. The results show that coating shapes, volumes, and wavelengths significantly affect the polarized radiative transfer characteristics.

Summary: The lifecycle of black carbon (BC)-containing particles from biomass burns is primarily influenced by changes in particle coating, with the coating mass increasing rapidly, then remaining relatively constant for a period before slowly decreasing. The initial increase in coating mass can be used to determine the formation rates of secondary organic aerosol (SOA).

Summary: The decline in atmospheric absorption over eastern central China due to anthropogenic Black Carbon (BC) emissions reduction is identified, and an emergent constraint on the effective radiative forcing from aerosol-radiation interaction (ERFari) of anthropogenic BC is established. The constrained range for the top-of-atmosphere ERFari over China is found to be higher than existing estimates, supporting the strong warming effect of BC over China and highlighting the need to improve BC simulations over source regions.

Summary: Black carbon aerosols have a significant impact on climate systems, and estimating their radiative effect requires understanding their mixing state and light absorption enhancement from coatings. Observations have shown lower light absorption enhancement factors (Eabs) than expected, leading to a debate on the true magnitude of BC's climate impact. However, considering the presence of extremely low-volatility (eLV) organics in BC coatings, the estimates of Eabs increase substantially. Our results highlight a strong radiative warming effect from atmospheric BC.

Summary: Measurements were conducted in a laboratory kitchen to investigate the types, emission factors, and ozone formation potential (OFP) of non-methane hydrocarbons (NMHCs) generated during various cooking processes. The results showed that NMHC emission factors varied for different types of cooking activities and types of food materials. Trichloroethylene, toluene, n-dodecane, isoprene, ethylene, and 3-methylpentane were identified as the NMHC species with the greatest OFPs during cooking. These findings provide valuable information on the impact of Chinese kitchens on indoor air quality.

Summary: Primary emissions of pollutants in China have decreased, but controlling secondary aerosol pollution remains a challenge. This study examined the characteristics of secondary nitrate and sulfate conversion in several cities and used interpretable attribution techniques to determine their contributions to PM2.5. The results showed a significant relationship between nitrogen oxidation rate and O-3 concentration, and higher humidity promoted sulfur oxidation. Jinan had more intense secondary conversion and pollution events were primarily caused by secondary formation and vehicle emissions. Machine learning and interpretable attribution techniques show potential for addressing environmental concerns.

Summary: This study investigated the presence of cyanobacteria on the pre-filter of HVAC systems and found that the concentrations were highest in autumn and significantly higher compared to winter and summer. The airborne transportation of aquatic and terrestrial cyanobacteria contributed to their presence on the pre-filter. The dominant cyanobacteria families identified were Chroococcidiopsaceae, norank_cyanobacteriales, Nostocaceae, and Paraspirulinaceae. Some detected genera, such as Nodularia sp., Pseudanabaena sp., and Leptolyngbya sp., potentially produced cyanobacterial toxins that could pose a threat to human health. This study provides new insights into the distribution of cyanobacteria outside of aquatic habitats.

Summary: The greening impacts in China from 2000 to 2017 increased vegetated areas and BVOC emissions. Accurate estimation of BVOC emissions is critical to understand their impacts on air quality. Different leaf area index (LAI) and land cover (LC) datasets were used to investigate the impact on BVOC emissions, and the effects on O-3 and SOA were evaluated. Results show that changing LAI and LC datasets of the model input has an impact on BVOC estimations, with the combination of C3S LC and GLASS LAI performing better. The uncertainties in MEGAN inputs should be fully considered in future O-3 and SOA simulations.
